    Run the preamp output (or line out or FX send) of one amp to the poweramp input (or line in or FX return) on the other. Be sure to dummy load the first one though, or you'll fry it.

    All it does is let you use the preamp of one amp with the poweramp of another. I don't think your two amps differ enough to make it worth the hassle.
